2-1-2-1. Cabling Requirements for TP Ports

⇒For Fast Ethernet TP network connection

The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of 100 meters.

⇒Gigabit Ethernet TP network connection

The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of 100 meters. Cat. 5e is recommended.

2-1-2-2. Cabling Requirements for 1000SX/LX SFP Module

It is more complex and comprehensive contrast to TP cabling in the fiber media. Basically, there are two categories of fiber, multi mode (MM) and single mode (SM). The later is categorized into several classes by the distance it supports. They are SX, LX, LHX, XD, and ZX. From the viewpoint of connector type, there mainly are LC and BiDi-SC.

Gigabit Fiber with multi-mode LC SFP module

Gigabit Fiber with single-mode LC SFP module

Gigabit Fiber with BiDi-SC 1310nm SFP module

Gigabit Fiber with BiDi-SC 1550nm SFP module

The following table lists the types of fiber that GSW-2690 supports and part of these models are available upon request.
